Finally the Fars authorities withdrew their force, probably on account of their relation to the suzerain court of Khwarazm, and Razi-u-Din, after experiencing some vicissitudes of fortune, obtained possession of the province, which upon his death he bequeathed to his son Malik Shuja-u-Din. Another new character now appeared at Kerman in the shape of a certain Borak Hajib/once an official of the Kara Khitai dynasty, who had transferred his services to Khwarazm, and was proceeding to India accompanied by a number of Khwarazm Amirs, with the intention of joining Jalal-u-Din. Malik Shuja-u-Din attempted to rob the party, but was defeated and put to death. Borak Hajib, feeling that it would be foolish to neglect such an exceptional opportunity, seized the province with the aid of Jalal-u-Din and made good his position. He attempted the life of his sovereign, as already narrated, and sub- sequently captured and strangled Ghias-u-Din, With the present of his head this disloyal, but only too successful, adventurer won the favour of the Mongols, and Ogotay not only confirmed him in his rule, but conferred on him the title of Kutlugh Khan. The dynasty played no part outside the Kerman province and does not appear to call for further notice.2 Christian Missions to the Mongols^ A.D. 1245-1253.—The invasion of the Mongols, and more especially the awful devastation wrought by them in Poland and Hungary, had excited much alarm and horror all over Europe, though not sufficient to cause a cessation of internal strife. When it appeared improbable that they would attempt to conquer Western Europe, the fear they inspired began to give place to the hope that they would shatter Islam, and rumours were also heard that there were Christian tribes among the new invaders. The views of Christendom found expression at the Council of Lyons, held in 1245, which decided that two embassies should be despatched to the Great Khan. Only one of these reached its destination. At its head was 1 Hajib signifies Chief Guardian or Chamberlain. In Ten Thousand Miles, etc., pp, 60-62, I have dealt with this dynasty more fully.
